The edge strip is intended for use when making floating floors as a floor separation, acting as a dilatation. The width of the tape used depends on the thickness of the constituent layers of the floor and should be selected so that after pouring the undercoat, the upper edge of the tape will protrude above the undercoat. After priming and hardening the foundation, excess edge tape should be cut off with a knife. It is made of foamed polyethylene LDPE with a density of min. 25 kg / m3, thickness 8 mm. Five incisions are made on the tape at intervals of 1 cm from the upper edge, allowing the excess edge tape protruding above the completed floor. In addition, it has an overlap of 25 cm wide PE foil used to cover the contact between the vertical (edge tape) and horizontal insulation (e.g. IZOROL boards).
